A French man has managed to blag his way into the most exclusive parties at Cannes - Gangnam Style!

The Psy imposter, named by French newspapers as Denis Carre, drank and partied with the stars for two days at the film festival.

Among those who fell for his disguise - which involved nothing more than a sparkly tuxedo and big round shades - was Skyfall actress Naomie Harris, who tweeted an image of herself posing with him at a party.

According to French newspaper La Montagne, Carre got the idea to impersonate the South Korean popstar after he was mistaken for him last year at a night club in Dublin.

"A crowd of people gathered around me, and the situation got totally out of control. We were only able to get out with the help of the bouncers. Then it happened again and again, to the point that the resemblance (with Psy) was causing problems in my private life," La Montagne reported him as saying.
